DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bird harm prevention device, and more particularly to a crow and other birds (especially crows) on overhead lines such as power lines and ground lines installed on telephone poles and towers. The present invention relates to a bird harm prevention device for preventing excrement damage and accidental contact with transmission lines.

[0002]

2. Description of the Related Art In recent years, birds (mostly crows) have frequently caused bird damage in power transmission accidents in urban areas. In most cases, when the crow stops and excretes on the electric wires or insulators disposed on the electric wire support portion (arm) of the electric pole, the excrement adheres to the electric wires or insulators, and the crow is attached to the iron wire. Is caused by contact between adjacent electric wires or a crow itself causing a short circuit between the electric wires, or a decrease in durability of the electric wires or the insulator.

[0003] By the way, various devices have been proposed as bird harm prevention devices for preventing nesting of birds such as crows and pigeons in high-voltage power transmission towers. That is, a plurality of support members are attached to a transmission line support portion of a steel tower, a rope is stretched between the support rods, and a bird such as a crow is prevented from stopping on an electric wire or an insulator. A structure in which a bird is prevented from stopping on a steel tower by attaching a supporting member to the tip) and attaching a stainless steel thin wire provided radially (hanging willow) around the supporting member in a rotatable manner so that birds do not stop on a steel tower. A stainless steel needle peak is provided at the wire support (arm end) to prevent birds from stopping on the tower. A perch is separately provided near the power transmission line support to guide crows and other birds to the location. The following configurations have been proposed.

[0004]

However, all of these bird harm prevention devices focus on prevention of nesting of birds such as crows on high-voltage power transmission towers and prevention of flying birds. There are issues like: That is, there is a difficulty in the installation workability in the device for stretching the rope. That is, especially in an urban area, it is necessary to perform installation work in a short time, but in this device, it is necessary to attach at least two support members and stretch a rope between the support members. The workability is difficult. The equipment for installing the needle hills and windmills is durable, but made of stainless steel. Therefore, the workability is inferior and the aesthetics of the city may be impaired. In addition, it becomes a hindrance when performing repair work. In the case of a device provided with a separate perch, it is not always possible to sufficiently attract birds such as crows to the perch. In addition, these devices cannot sufficiently cope with urban areas where transmission lines are stretched in various directions from utility poles. Although it is possible to prevent flying birds at the power transmission line support portion (the end of the arm) in a utility pole or tower, it cannot prevent the power transmission line itself from stopping. And other issues.

Therefore, the present applicant has previously proposed that "a support member is attached to a transmission line support portion or a fixing device which is detachably fixed to a transmission line, and the distal end or the intermediate portion of the support member has a free end. A bird harm prevention device in which a swingable insulating thin wire is attached above the electric wire and along the length of the transmission line ”(see Japanese Patent Application No. 8-195746). And since this bird harm prevention device is mounted on a power transmission line, it has an advantage that crows and the like can be prevented from flying to the power transmission line. However, since the insulating thin wire is attached to the power transmission line with a fixture such as a clip, the stability at the time of attachment may not be sufficient.

According to the present invention, there is provided a bird harm prevention device capable of mounting the bird harm prevention device more easily, simplifying the structure thereof, and stabilizing the state of attachment to a power transmission line. Is to do.

[0007]

According to a first aspect of the present invention, as a means for solving the above-mentioned problems, there is provided a bird harm prevention device according to the present invention, which is an overhead line such as a transmission line or a ground line installed on a telephone pole or a steel tower. A bird harm prevention device for preventing bird damage caused by a crow or the like to a coil, which is detachably wrapped around the overhead wire and is attached in a coil shape, the overhead wire wrapping mounting device engaging with the outer periphery of the overhead wire, and the overhead wire wrapping mounting device A tip attached above the overhead wire and along the length direction of the overhead wire has a free end and a swingable insulating thin wire.

According to a second aspect of the present invention, in the bird harmful rod device according to the first aspect of the present invention, a thin wire mounting rod extending vertically to the overhead wire is extended at one end of the overhead wire winding attachment.
The insulating thin wire is detachably attached to a tip or an intermediate portion of the thin wire attaching rod.

A bird harm prevention device according to the present invention is a device for preventing bird harm by being detachably mounted on, for example, a transmission line installed on a utility pole or a steel tower in an urban area, and wound around the transmission line. A swingable insulating thin wire, which is directly or indirectly attached to the wire-wound mounting device that has been wound and mounted, has a free end above the power transmission line and a free end along the length direction of the power transmission line. When birds fly and try to stop, they oscillate by contact with the birds themselves, and when multiple birds are installed, they are lined up above the transmission line. The scene of whether the line of is arranged is brought out.

[0010] Here, the insulating fine wire is FR.
P, polycarbonate, acrylic, and other synthetic resin wires having strength are preferable. As the length of this wire, a length of about 0.5 m to 2 m is used.
Preferably, the length of the support member is set to be 0.25 m to 1 m in the length direction of the transmission line (stretching direction). If the length is too long, the fine wire contacts the power transmission line, and if it is too short, the strength of the fine wire becomes too strong, and the oscillating property decreases.

[0011]

As is apparent from the above description, according to the bird harm prevention device of the first aspect of the present invention, it is possible to wind the power transmission line with the coil-shaped wire winding mounting tool and detachably mount it. Because it can be installed and removed easily, there is no risk of falling off even by wind or vibration, and a swingable insulating thin wire with a free end is placed above the transmission line,
And because it is installed along the length of the transmission line,
The insulating thin wire has an effect that birds such as crows can be prevented from stopping on the transmission line. Further, since the insulating thin wire is made of an insulating material, it has an effect of preventing the possibility of causing a short circuit accident even if it swings, bends or falls due to wind. Further, even in the case where a plurality of wires are attached, the thin insulating wires are arranged as a single line above the power transmission line, so that there is an effect that the cityscape is not spoiled.

According to the bird harm prevention device of the second aspect, a thin wire mounting rod that stands upright in the direction perpendicular to the overhead wire is extended at one end of the overhead wire wrapping attachment, and the distal end or the intermediate portion of the fine wire mounting rod is extended. In the form of detachably attaching the insulating thin wire to,
Since the configuration is simple, there is an effect that replacement and length adjustment of the insulating thin wire can be easily performed.

It is a front view.

The bird harm prevention device according to the present embodiment is a bird harm prevention device for a transmission line stretched over a utility pole in an urban area. As shown in FIG. An overhead wire wrapping attachment 5 attached to a power transmission line 4 laid through the two insulators 3 and an insulating thin wire 6 detachably attached to the overhead wire wrapping attachment 5.

The overhead wire wrapping device 5 is a coil-shaped mounting device for fixing the power transmission line 4,
And a thin wire mounting rod 8 extending upward from one end of the coiled winding portion 7. The overhead wire wrapping attachment 5 is formed of a wire (metal wire or the like) having a surface subjected to insulation treatment, and a part of the wire is turned in a coil shape.
This portion forms a coiled winding portion 7, and one end side that is not turned in a coil shape is bent upward and erected, and this portion forms a fine wire mounting rod 8. As this wire, a metal wire having a diameter (φ) of about 1 mm to 3 mm with an insulating coating applied to the surface is used.

The coiled winding portion 7 has a coil inner diameter d ₁ which is the same as or slightly larger than the outer diameter d ₂ of the transmission line 4 which can be engaged by being wound around the transmission line 4. Usually, it is about 1 cm to 3 cm depending on the dimensions of the transmission line 4 and other overhead lines. That is, it is important that the coil-shaped wrapped portion 7 can be engaged with the power transmission line 4 so that the coil-shaped wrapped portion 7 is not easily displaced or dropped by wind or the like. The thin wire mounting rod 8 has an insulating thin wire 6 at its upper end.
Is provided with a thin wire holding section 9 for detachably holding the thin wire. The thin wire holding portion 9 is formed by bending the upper end of the thin wire mounting rod 8 in a direction parallel to the axis x of the coiled winding portion 7. In other words, the thin wire mounting rod 8 is wound once or several times to form an arc 9a into which the insulating thin wire 6 can be inserted, bent in a direction parallel to the axis x of the coiled winding portion 7, and bent at its tip into a concave shape. And a thin wire supporting recess 9b for supporting the insulating thin wire 6 from below.
Thereby, the insulating thin wire 6 is supported by the thin wire supporting concave portion 9b, and the tip thereof is inserted into the arc 9a.
The insulating thin wire 6 can be mounted in a direction parallel to the axis x of the coiled winding portion 7, that is, above the power transmission line 4 and in parallel with the length direction (stretching direction).

In this embodiment, the insulating thin wire 6 is
Although the length of the transmission line 4 extends in one direction, the transmission line 4 may be attached in the left-right direction. In the case of mounting in the left and right direction, it is preferable to provide the thin wire holding portion 9 at the left and right positions where it is not touched on one side. The insulating thin wire 6 is made of a wire made of FRP, polycarbonate, acrylic, or other synthetic resin having strength, and has a total length of about 0.5 m to 2 m. When the transmission line 4 extends in one direction, the length of the transmission line 4 is set to 0.25 m to 1 m in the transmission line length direction (stretching direction) around the thin wire mounting rod 8. If the length is too long, the fine wire contacts the power transmission line, and if it is too short, the strength of the fine wire becomes too strong, and the oscillating property decreases.

The bird harm prevention device according to the present embodiment comprises a wire wrapping attachment comprising a coil-shaped wrapping portion 7 on a power transmission line 4 stretched via an insulator 3 to a power transmission line support portion 2 of a utility pole 1 in an urban area. 5 is a device for preventing bird harm that detachably fixes 5. First, the overhead wire wrapping attachment 5 of this device is detachably attached by wrapping it around the bird harmful transmission line 4, or the insulating thin wire 7 is removed from the coiled winding portion 7 of the overhead wire wrapping attachment 5 before attachment. The thin wire supporting concave portion 9 of the thin wire holding portion 9 at the front end or intermediate portion (here, provided at the front end portion) of the extended thin wire mounting rod 8.
By being inserted into the circular arc 9a while being supported by b, it is arranged above the power transmission line 4 and along the length direction of the power transmission line 4, usually at regular intervals in parallel with the power transmission line 4.

As a result, a bird such as a crow flying to stop on the power transmission line 4 will be disturbed by the insulating thin wire 6 located above the power transmission line 4. The thin wire 6 is prevented from swinging and stopping. Therefore, bird damage can be prevented by the insulating thin wire 6. Further, since the insulating thin wire 6 is formed of an insulating material, accidents such as short-circuiting of the transmission line 4 can be prevented even by vibration such as wind. Further, the bird harm prevention device can be easily detached from the power transmission line 4 by turning the coiled winding portion 7 in a direction opposite to that at the time of mounting.

It should be noted that the present invention is not limited to the embodiments described below, but includes configurations that can be modified and implemented within the scope of the present invention. In the above-described embodiment, the description has been made in the form in which the insulating thin wire and the overhead wire wrapping attachment can be separated, but as shown in FIG. It may be. For example, the thin insulating wire 6 and the overhead wire wrapping attachment 5 may be formed of the same material and continuous.
